Fully automatic soft-top
The fully automatic soft-top, like the standard soft-top, consists of magnesium and aluminum
components.
The soft-top lowers and raises fully automatically by means of electrohydraulic servo units
that control the primary soft-top movements. The soft-top/windscreen top rail locks are
operated by an electric motor.
The soft-top is raised and lowered by pressing the soft-top switch located between the
gear lever and the ash tray - no additional manual operations are required.
The inner lining provides a neat, coupé-style interior effect, and significantly improves the
soft-top acoustics and heat insulating properties.
The fully automatic soft-top is available as an optional extra.
System overview
The hydraulic pump unit is mounted on the left soft-top main bearing.
Hydraulic pump unit
The hydraulic pump unit consists of an oil reservoir with an integral pump. The pump is driven
by a DC reversing motor. All hydraulic valves are integrated in the hydraulic pump unit.
Method of operation
:
To change the direction of movement of the folding soft-top, the direction of rotation of the
hydraulic pump motor is reversed. The hydraulic pump only operates while the soft-top is
being moved.
The operation of the pump and locking mechanism are controlled by the CVM IV control
unit as required on the basis of the soft-top switch setting.
A temperature sensor protects the hydraulic pump unit against overload. There is a temperature
sensor fitted to the hydraulic pump unit (similar to E46/C). At a temperature of 105º
Celsius the pump is prevented from operating in order to protect the hydraulic system from
damage. The soft-top can then only be operated manually.
There is no facility for topping up the hydraulic fluid on this sealed hydraulic system, nor is
it necessary. The hydraulic system has a self-bleeding function which is activated by repeated
operation. In order to replace the hydraulic pump unit, the soft-top frame has to be
removed.
Hydraulic servo units
The folding soft-top is moved in two directions for lowering and raising by two doubleaction
hydraulic servo units. The hydraulic servo units can only be replaced in conjunction
with the soft-top frame as a whole.
There is one hydraulic servo unit on each side of the soft-top frame (in the main pillar) on
the main bearings. The hydraulic pump unit is attached to the left hydraulic servo
unit.
Preconditions for raising and lowering the soft-top
Before the soft-top can be moved, the following preconditions must be met:
1. Neither window detected as closed by the basic module
2. Vehicle stationary (road speed < 5 km/h)
3. No hardtop fitted
4. Ignition key position at terminal R at least (except for Easy Open/Close function)
5. System test reports no faults
6. No short circuit and no circuit break present
7. Outside temperature is above minimum limit
Preconditions 1 to 7 must be satisfied simultaneously.
Lowering the soft top
Sequence:
1. Windows are lowered (window regulators are operated for 1.5 seconds if a closed win
dow is detected)
2. Soft-top is released from the windscreen top rail
3. Soft-top is folded backwards
4. Soft-top is stowed in stowage compartment and locked in place
5. Locking latches are retracted while pump is still running
6. Red LED goes out
7.Windows are raised (2 seconds after soft-top locks in position)
Raising the soft top
1. Windows are lowered (window regulators are operated for 1.5 seconds if a closed win
dow is detected)
2. Locking latches are extended and the stowage compartment catch is released
3. Soft-top is lifted out of stowage compartment
4. Soft-top is raised forwards
5. Locking latches engage in windscreen top rail
6. Locking mechanism is activated, moves to "LOCKED" position and stops on reaching
the limit switch
7. Red LED goes out
8.Windows are raised (2 seconds after soft-top locks in position)
Note:
If the soft-top button is released while the raising or lowering sequence is still in progress,
the movement of the soft-top comes to an immediate halt. Because the drive system does
not lock, the soft-top is then held only by the inherent resistance within the mechanism and
the hydraulic servo units.
Pressing the button again restarts the interrupted movement.
Easy Open function
An automatic sequence of operations for lowering the soft-top can be activated using the
ignition key in the driver’s door.
Sequence:
1. Insert ignition key in driver's door lock
2. Turn key anti-clockwise and hold. The basic module immediately sends the "Easy Open"
signal to the soft-top module.
3. The window regulators are then operated by the CVM control unit within 1.5 seconds.
Windows are lowered
4. Remaining sequence as for "Lowering the soft-top", steps 2 to 7

Complete Vehicle
5. Remove ignition key from door
The Easy Open function is not possible after terminal R.
Easy Close function
An automatic sequence of operations for raising the soft-top can be activated by locking
the driver's door.
Easy Close sequence:
1. Insert ignition key in driver's door lock
2. Turn key clockwise and hold. The basic module immediately sends the "Easy Close"
signal to the soft-top module
3. Remaining sequence as for "Raising the soft-top", steps 2 to 7
4. The window regulators are then operated by the CVM control unit within 1.5 seconds.
Windows are closed.
5. Remove ignition key from door
Note:
If the signal from the soft-top module IV is not received, the basic module activates the
automatic "Close All" function. The Easy Close function is not possible after terminal R.
Emergency actuator
If the electrics or hydraulics fail, the soft-top can be raised/lowered by means of the emergency
actuator.
To raise the soft-top using the emergency actuator, the following procedure must be followed:
- Open bypass circuit on hydraulic pump unit by pulling cable.
- Release soft-top stowage compartment catch by pulling cable.
- Raise soft-top to windscreen top rail by hand.
- Engage windscreen top rail lock using Allen key.
For lowering the soft-top with the emergency actuator, the procedure is reversed.
Opening bypass circuit on hydraulic pump unit:
In the boot on the left-hand side below the soft-top stowage compartment base there is a
release cable with a plastic pull handle. The plastic pull handle is pulled out as far as it will
go and then locked in that position by turning it through 90º. This opens a bypass circuit
in the hydraulic pump unit. The soft-top can then be moved by hand.
